Title: Probe for oscilloscope
Inventor: YAZAWA HISANOBU
IPC: G01R13/20
Filed: 1989-11-21
Abstract: PURPOSE:To reduce the size and weight of the device by incorporating a D/A converting device in a probe. CONSTITUTION:This probe 20 inputs an (n)-bit binary digital signal at an input terminal 21 and converts the signal into an analog value by a D/A conversion LSI 22, which is driven tough a power input terminal 24, a clock signal input terminal 25, and a ground input terminal 26, with a timing signal inputted to the terminal 25. Then (n)-bit binary signals are weighted, added, and converted into one analog signal. This signal is outputted from an analog signal output terminal 23. Thus, the digital signal is converted by the internal LSI 22 and the device is reduced in size, weight, and cost. Further, the probe 20 outputs the analog signal, so the oscilloscope 10 needs to have only an analog signal connector and this probe is replaced with an analog signal probe 20 for analog signal measurement.

Title: Method for converting heat energy into mechanical energy and heat engine
Inventor: TANAKA TSUYOSHI
IPC: F03G7/00
Filed: 1987-12-01
Abstract: PURPOSE:To convert heat energy into mechanical energy with a simple structure by heating or cooling a magnetic substance set up between opposed magnetic fields. CONSTITUTION:A magnetic substance 1 is set up between magnetic fields 2 installed as opposed with polarity where these magnetic fields 2 are repulsed to each other. Since magnetic susceptibility in the magnetic substance when it is less than the specified temperature, each magnetic field 2 comes nearer to the magnetic substance 1 by dint of magnetic attraction. When the magnetic substance 1 is made to be more than the specified temperature, the magnetic susceptibility in the magnetic substance 1 comes to almost 0. Thus, the magnetic substance 1 is heated to be more than the specified temperature or cooled to be less than the specified one, whereby these magnetic fields 2 or the magnetic substance 1 are moved. Consequently, if heating and cooling are repeated, such a heat engine that reciprocates can be constituted.

Title: Shadeless light
Inventor: NAKADA TOMOHARU
IPC: A61C19/00
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a shadeless light which can easily prevent dust form attaching to a reflecting mirror of the shadeless light with no maintenance and can be used with excellent light efficiency for a long period of time. SOLUTION: A reflecting mirror 3 of a shadeless light is exposed to the light for a light source 2, therefore titanium oxide film 3a is formed on the surface of the reflecting mirror 3. While the shadeless light is lighted, moisture and oxygen in air are decomposed at the surface of the reflecting mirror 3 (the titanium exide film 3a) thereby keeping the surface of the reflecting mirror wet (hydrophilic state). As a result, dust attaching to the surface of the reflecting mirror 3 by an electrostatic force will be prevented.

Title: Communication device
Inventor: MATSUDA YASUMITSU
IPC: H04L69/40
Filed: 1987-11-30
Abstract: PURPOSE:To improve transmitting efficiency by continuously executing data transmission before the generation of abnormality when the abnormality is recovered and a time counting is not finished. CONSTITUTION:When the abnormality is generated in a main power source 5 during the transmission of data, which are stored in a memory 3, through a communicating interface 4 to an opponent station and the main power source 5 is recovered after the transmission can not executed, a CPU1 discriminates whether a timer 2 finishes the time counting or not. When the timer 2 finishes the time counting, the opponent station already goes to a condition that the data transmission is not received and on the other hand, when the timer 2 continues the time counting, the opponent station is in a condition that the data transmission is received. When the timer 2 finishes the time counting, the timer is started again by the CPU1 and the transmission is re-executed from the first step. Then, when the timer 2 does not finish the time counting, the data transmission before the abnormality of the main power source is continuously executed. Thus, the transmitting efficiency is improved.

Title: Driving method for optical bistable semiconductor laser
Inventor: KUNO MASAAKI
IPC: G02F3/00
Filed: 1986-12-19
Abstract: PURPOSE:To make it possible to turn ON optical bistable operation even with very weak input light, to drive a device with the very weak input light purely optically and to make it possible to drive the device suitably for the integration of low input-light intensities without losses in optoelectronic and electrooptic trnasduder actions, by superimposing bias light on the input light, and turning ON/OFF the bias light. CONSTITUTION:Input light intensity PIN is obtained by superimposing bias light intensity B and signal light intensity Psig through a half mirror 4 or a wave combiner such as a coupler. On the PIN-POUT graph, the signal light intensity Psig is superimposed on the BON, where BON and BOFF are the ON/OFF intensities of the bias light intensity B. BON and Psig are selected at levels, where the output light POUT can undergo transition to a high level. When the output light undergoes transition to the high level, this state can be heled without the input light PIN. The level of the BOFF is selected so that the optical bistable state can be recovered to the initial low level with the OFF intensity BOFF of the bias light. Thus the light output can be turned ON/OFF with the very weak input light, and the amplification effect is obtained.

Title: Production of calcium aluminate-containig slag
Inventor: TANAKA YOSHIO
IPC: C04B103/14
Filed: 1988-12-02
Abstract: PURPOSE:To efficiently obtain the subject slag without problems of dusting, etc., in steel making factories by adding an alumina and lime sources to a steel making slag in a molten state so as to provide the subject slag with a specific composition and producing the slag. CONSTITUTION:An alumina and lime sources are added to a steel making slag formed as a by-product in steel making factories to produce a calcium aluminate-containing slag. The amounts of the alumina and lime sources added in the process are varied depending on the chemical components of the steel making slag and the chemical components of the synthesized product slag are 25-38wt.% Al2O3 and 1.0-1.8 ratio of CaO/Al2O3. If the amount of the Al2O3 is lower than the lower limit, product slag having high characteristics with a high content of calcium aluminate is not obtained and hardening performance of a quick hardening material obtained by using the slag is inferior. A larger amount than the upper limit is unfavorable in aspects of cost. Furthermore, if the ratio CaO/Al2O3 is lower than the lower limit, 12CaO.7Al2O3 (C12A7) which is a quick hardening component is not produced. If the ratio is higher than the upper limit, hardening performance is also deteriorated and unfavorable in the aspects of cost.
